How to Fix CVE-2026-85135

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-85135, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A security flaw has been discovered in ILIAS up to 9.21/10.9/11.2. This affects the function ilObjMediaObjectGUI::uploadMultipleSubtitleFileObject of the file Services/Repository/Service/Resources/ZipAdapter.php of the component MediaPool. The manipulation results in unrestricted upload. The attack may be launched remotely. Upgrading to version 9.22, 10.10 and 11.3 is able to mitigate this issue. The patch is identified as ef5d7f99fe1ea0381db04b333a2906548b3590e4/b0d61be43671b6bfe91baf469a5ee11e764f2e23. It is recommended to upgrade the affected component.
